OK - so I've also done a couple of gigs with this head into a single 8ohm TKS 1x12.
The first one was a party in a hotel with a full band. I had PA support, but no bass in the monitors, so I had to turn up to give a bit of stage coverage. Last night's gig was with a lively, energetic acoustic trio in a packed, noisy pub. No drums, but the bass has to be there because it's down to me to drive it.
The WB-100 puts 120w into 8ohm, too - my goodness it kicks. It's tactile, rich and fat. At both gigs I half-expected to hit its ceiling, but I'm amazed at how solid it sounded. 120 old-school watts goes a LONG way.
It's just gorgeous.
